A systematic study has been carried out to quantify the effect of microcrystallite nucleation in the intrinsic layer of protocrystalline Si:H p-i-n solar cells prepared by rf plasma enhanced chemical vapor deposition (PECVD). Real-time spectroscopic ellipsometry (RTSE) results that have previously identified the transitions from amorphous to microcrystalline phase were confirmed with atomic for...

in spite of the importance of teacher's motivation only a limited number of studies have been conducted on teacher's demotivation in iran. this study was an attempt to investigate demotivating factors among iranian efl language institute teachers in terms of years of teaching experience. to this end, the researchers tried to utilize a questionnaire as a research method. to collect dat...

knowledge transfer was the most important factors of success for organizations in today's complex and changing environment as one of aspects of knowledge management. the aim of this study was to investigate the relationship between intrinsic motivation and extrinsic motivation by transfer the employee’s knowledge in social security organizations in kerman. the method research is descriptiv...

in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...

this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

in our previous work, the effect of use of a water soluble cdi/nhs system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. in this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by cdi/nhs system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...

This research uses the Repertory Grid technique to understand intrinsic factors influencing benefit maximization of IS usage. The results show that domain-relevant skills, task motivation, cognitive/work style attributes, individual characteristics (identified as creativity traits) and personal characteristics (identified as innovativeness traits) influence benefit maximization of IS usage. The...

This paper presents a Multi-agent System and a Methodology to select and to integrate heterogenous and distributed information sources to make recommendations. A set of intrinsic characteristics has been defined. These characteristics allow having a description of the information contained in the sources to select the most relevant information sources. Ontologies are used to integrate the infor...
